Knowledge Of Coking Coal

When coking coal to gasification coal ratio is 7, there is sufficient hydrogen supplied by the COG tri-reforming. The WGS unit can be cancelled in the new COG-CTM process, as shown in Figure 4.As the WGS unit is no longer needed in the COG-CTM process, the main operating parameters of the AGR unit and TRM unit will change accordingly.
